Abstract
Inclusive neutral meson production spectra have been measured in a wide $p_{\rm T}$ range at mid-rapidity by the ALICE experiment in pp collisions from $\sqrt{s} = 0.9$ to $13$ TeV, p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ and $8.16$ TeV, as well as Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ and $5.02$ TeV. $\pi^0$ and $\eta$ mesons are reconstructed in their two photon decay channels using the invariant mass techniques. The photons being detected with two complementary methods: photons converted to $e^+e^-$ pairs in the central barrel detectors’ material or directly registered in the ALICE electromagnetic calorimeters, EMCal and PHOS. An overview of the recent results from ALICE on mesons production in pp, p-Pb and Pb-Pb collisions is presented.
